Diagonal braces E E' l .extend forward from the blocksD D', which fform 4the ends of the axle, tothe perch C, they 'heing'ilrn'ily fastened to'hot'h axle and perch. The main frame of the machine thus 'consists `of the axle A, 'perch C, and diagonal braces E E'; but it may be constructed inV any ccn- -venient form. Across perch and bracess arrangeda long seed-box,^F, as usual in seeding-machines, and inthe bottoni of thisseedboxJ are arranged hoppers G G, containing toothed distribntingcylinders H H, operated by'aiongshaft, I, commonto all the cylindersand driven by gearingjfrom thedrivingwheel,

as "hereinafter 'descri'ned.A These. cylinders.r have 'separate'.bearingsJ'J,`sothat if the-shaft` be'removed they will still-retain their respect-- -ive positions in the hopper, and fthe shaft passes loosely thronghfthem, sothat it may not bind andcan be taken ont, and one or more of the hoppers and cylinders removed for ree .position of mellor' le Bref-Devilman with the seed'ib ille fr lriliba M.; militaires@ l hopper-spent hymeans of hinges,[as at N. 1 `It i 1mg wm desirable mni whxclifisz-hingcd tothe diego Iinei with the lower ends of the nerto the under side of the main fral'nc.` To this drill-bar 'are attached the drills() 0, so arranged andl formed' as to drag oritrail upon the" ground in rearo-ty the drillbar without accumulating rubbish or becoming clogged. They are hollow tubes, as shown, and have a cutting-shoe, P, the sides ot', n'lchiorm a sharp "angleat thelower pointto enter the earth more readily-.- The shanks 'of these drills are attached to the drill-har-M by spring .cotilleoti ons Q, Q, as shown, formed ot' steel or other suitable material, and these springs are rigidly attached at one end to the shank ot' the drill,

and'at theother end rigidly tothe drill-'ba r. for the threefold purpose: lirst, to prevent. their moving laterally, that the seed may be planted in'rows' of equal distance apart; second, that ,the 'drills may be flexible up and "down, and

lthus conform to any unevennessof the ground and move overall rubbish and other obstructions 4which fmightfotherw-ise break o`r clog them; -third,"that by the use 'ol' a lever common to them all'the drills can be forced into or raised out of the ground simnltz'lneously.

' The under side ot` the drill-Shanks are curved separately,tovrise and fall to pass over olist ructlonswithontdisturbmgtherest,asshown by red lilies in Fig. 2.

Funnels S S are arranged' upon the upperV ends ot the drills to receivethe grain discharged' from the hoppers through the ducts LL, and from them it passes in to and -down through thedril'l-tubes and into the furrow formed-by the sliced".

The arrangement forraising the drills and pressing them into the ground is as .l'ollo'ws:

1 To the drill-bar M, near its center, is tirmly fastened a /1ever,-',l, :composedvot two arms united by a'rod.y `Asingle arm may be used;

,but l prefer adonble lever, as the Astrain -is more equally distributed.` To the rod joining these arms, or, if a single lever be be used' to its outer end, is pivoted a link, U,'whose upper c nd is pivoted to one arm of an L-shapcd lever, V, pivoted at i ts elbow W to the perch' lO of the'mach'ine, thc upper end ot' V being` within reach of the drivcrin his seat at X.

Thus, if the driver-or operator wishesto raise l the drills clear of thc ground, he pullsthehan dle ot' the lever V toward him. The other end of Vis elevated, turning upon the pivot or fulcrunrW at its elbow, and drawsnli the link U, which raises the end of the arm T, attached to the drill-bar. Thus, as the ann T isl rigidly n `fastened to the drill-bar, the latter mus'tturn -nponits hinges and raise the drills. The 1evers, drill-bar, and drills will'thcn be caused to'assume the position shown 4by red' lines in Fig, 3, 'and may be there retained by any suit able `stop, or catch. In the drawings' asegconvenient way.

I ment of a circle, Y', made of metal and having l for its center the pivot W, is-.shown fastened tothe perch .0, between it and the lever V, and pierced with 'a number of holes. Abracket, Z, upon the lever V clasps this segment, and assists in retaining the lever in its upright pesitioa, and close. to the metal segment. This bracket hasta hole in it corresponding in size and distance from the pivot W with the holes inthe segmentY, and into this hole tits spin or projection at the lower end ot the rod a, which .is ben t, as shown, and pivoted at or near its center to the lever V. Aspring iszaranged Abe'tv'veen the upper ends ot' lever V and rod a, w h ich presses the rod awa y from the lever, and consequently as the rod is pivoted. to the lever the pinor projection at its lower end is'kept pressed into the hole in the bracket Zand into one ot' the holes in lthe metal segment X, thus retaining the leverV, and consequently the-drill-bar and drills,.in anyvrequired position. I't tlier position Ais to 'be' altered, the

driver takes hold ofthe handleslof both lever and rod and presses theni together, thusthrowing' the retaining-pin ont of the hole. in the segnient, The levcr..is then movedruntil the pin comes oppositethe desired hole in the segment. When the roda is released the spring presses its upper end away from the lever V, yand thus throws the pin' into the hole desired, and the lever and drills are retained in their new position."

My improved arrangement of gearingtov alter and regulate the amount ofgraiu te be sown per acre is 'astollowsr4 Upon the hub of one ofthe supportingwheels, as B, and inside the whecl,I arrange a nest ot' helical gearing consisting' ot' several series of spiral cogs, b' b2, of .different pitch, whereby the ratio be tweenthe velocities of the pinion c and of the driving-wheel B may be varied at' pleasure. The pinion c maybe moved and held in gear with one or other` ofthesc series of cogs in any. 1 prefer to arrange it as.

shown in the drawings. The shaftdof the pinion c has bearings in a' block, e, hayinga metal lear,j", fastened to it. Holes gg'g, corresponding in number to the' number ol. series ot' spiral eog's upon the hub of the drivingwheel, are bored in thismet'al ear. A universal' joint in' the shaft d, at IL, allows the pinion 'c to .be shifted to one side or other in the arc ot' a circle. 'lhhus by means of a set-screw, i,

the metal ear j' may be clamped fast to the di agonalbrace E of the main frame-and the pinion c'held in gear'with one or other of the series of cogs, as desired'.A Any convenient number of these, series of spiral cogs may be ar` ranged upon the hub of the driving-wheel. Asthe pitch is variedthe number of cogs varies also. I prefer to arrange the first, as b,

'with eight engs, the second, b', with teu, the

third, b2, with twelve cogs, and so on.
